12GA Rifle From Hell

Here is picture of a jacketed hollowpoint
12ga slug a fellow is going to make for us.
We hope to have tooling set up this summer
we plan on. Next to it is a 600gr Dixie hardened
slug. First ones he will probably make will
be about 700-750 gr.Ed

The hollow pointed slug above can have a
light plastic/rubber nose for streamlining for
better BC, for 2-300 yard shooting.
In the 87 Win Levergun, smooth barrel,
long barrel, using brass RMC 3" cases,
1 oz Brenneke KO slug to 2700 with 4227
powder. Shotgun primer. I will be getting
some 3.5" RMC brass that he will put a special
longer corner radius in, to allow faster loads
with less case expansion and easier resizing.
Should get same slug to 3000 and resize
easier also. With shotgun primer able to use
4227, and you WON"T have to rework hammer
or firing pin to do big primers.ED
 
Santa sent me 9 more PROP cases used in little
cannons for bomb disposal. In pic, 2 on the left
are our originals, next 3 are resized PROP
cases, exactly matching ours, and then 9
to be resized. Ed

Here is picture of the Enfield bolt,
showing the 2 rear lugs I added.
The huge bolt handle base is 3rd lug.
Bolt handle needs polishing.This one
will be in the action for the 8GA FH.Ed

Here is picture of the 4 slugs I've used in
the 28GA FH load developement in the
3.25" long brass case and they
also work in the plastic cases. Ed

THE 8GA FH BELLERED TODAY. It is in Enfield I rigged with
rear locking bolt lugs. 32" barrel, tested 3.3" plastic cases.
Cases are the REM kiln gun cases. With the double cup base.
I shaved base a little so that chamber will fire these as well as
regular 8ga plastic. None of the firing today expanded base cups
at all, so they are real strong cases. Started testing to check
ignition with shotgun primers and to see if cases are any
good. Starting with a 110 gr mouse ball, wad under it, and 150 gr
of Blue Dot, about 5000 fps.. Gun didn't even recoil.Then a
410 gr one at 3000 fps, Then a 770 gr hollowbase slug in a wadcup
up to 2000 so far with 180gr of 7383. Barrel is smoothbore. 832"
bore at the muzzle. Ed

Mouse ball?

Is it hollow? I'm trying to picture a 110gr 8ga lead ball, but I'm not having much luck...

Is it plastic or something?
 
It is hard rubber computer mouse ball. The heavier 410 gr one has
steel ball inside. It was just something lighter than lead to start
load and gun testing with. Ed
 
Some 8GA FH testing- using IMR 4759, 770 gr slug,
top load of 140 gr, got 2500 fps......
Over 10,000 ft lbs..Cases extract easy.
The plastic in 8ga case is twice as thick as
in 12ga cases. Tried 4227 and case is too large
diameter for dependable ignition.So it's
old dependable 4759..Ed
 
Here is picture of Enfield 8GA FH. You can see plastic case
in the port. Box of cases behind, 770 gr and 1050 gr
slugs in front with the 8ga wadcups I use.
Left two slugs are 1050 gr made from 3 oz kiln slugs.
I rounded nose and put in hollow base. Also the
cards and fiber wads used. Slugs are hollowbase, as
it is smooth bore barrel. Ed

In picture of the 8ga bolt action you can see the
ring I put on front of bolt to support large diameter
8ga casehead. It is suported against thrust by the
front lugs, and total bolt thrust is supported by rear
lugs and have taken the heavy loads ok.. Ed
 
Here is picture on left of the 12ga hollowpoint slug
with plastic tip. Makes it streamlined, good for 300yds.
And still will expand good thin skinned game-deer.
I put tip in with glue gun in few seconds, and
shaped a point on it with trim knife. Ed

I also have two other cartridges with my name
on them that I am promoting. They are my 700HE
and my 585BHE. They both belted straight cases.
Montana Rifle company is coming out with their
big PH action and some guys will be doing my
cases in them.

Info on the 585BHE. It will work in
any gun that handles 505 Gibbs like Enfield, CZ,
Ruger,etc.Mine is in Enfield.Here is picture of
of one next to Trex. And mine holds 15gr more
powder than that Trex case. 585BHE will do 750
grain from 1800 to 2800 fps in my Enfield.

Anyone interested setting up a gun, contact me
I will furnish reamer and 15 free cases. Cases are
headstamped. When done return reamer to me, for
the next guy. I will keep them sharpened. After a
few guys have guns we all will get together with
others wanting some and get a run of brass made.
I'd like guys to ask for reamer when gun is going
to be ready to chamber, that way reamers get the
most guns done in shortest time.Ed

On Fri May 2 8pm on the Science Channel ,they will have
an article about the heavy barrel cannons that shoot
the brass cases for bomb disposal.They are the same as
our 12GA FH case,when resized in my dies and are shown
in this thread a couple months back in picture.
It will show them using them for bomb disposal. Ed
 
Testing 8GA FH in Enfield, 1050 gr slug in wad cup, 120 gr
of 4759, over 2000 fps. Cases extract easy. Hardly any
base cup expansion...Ed
 
Here is picture of a sectioned 8ga plastic case
showing how heavy and strong it is built. The
plastic is one piece compressioned formed and
the sides of the cases are twice as thick as
12ga cases.You can see the double thickness
of the base cup. Ed

Here is picture of the bolt setup for the 8ga
Enfield we did.Also comparison to a Mauser
12ga shotgun bolt conversion, from which
I got the concept. Ed

I was asked how I got 8ga heavy barrel so quick.
First it is smoothbore, second a 110 bucks total shipping and all.
First I bought a 1.5 inch dia 4130 alloy, heat treated, shaft,
32" long. Then I had a deep hole drilling company drill
a .832" hole in it. Came out centered on both ends.
Then after it got here I used cylinder hone to polish
the inside of the bore. Threaded it, chambered it, and put
in the Enfield bolt action. The heat treating it had was just like
the barrel stock that barrel guys get. Ed.
 
For those wanting to see video of the 12GA FH in
the Savage busting big pail of water, one of the
kids posted it on Youtube- Titled "Grampa's Cannon".
I just found out that it is on there.
This was the video that the still pictures posted
before, was takem from. They have the sound
muted so as not to hurt camera sound system. Ed
